ABSTRACT:
A microbe-specific medium for detection of vancomycin-resistantEnterococciin a test sample within 24 hours and preferably within 18 hours. The testing medium provides a selective growth medium for vancomycin-resistantEnterococciand includes specific nutrient indicators which only the target microbe can significantly metabolize and use for growth. The nutrient indicator contain a nutrient moiety and a detectable moiety linked together by a covalent bond. The nutrient indicators produce detectable signals only if the nutrient indicators are hydrolyzed by theEnterococcispecific enzymes including β-glucosidase and pyrrolidonyl arylamidase.
